    Atomistic simulations indicate the c-subunit ring of the F1Fo ATP synthase is not the mitochondrial permeability transition pore

    Wenchang Zhou et al.
    The notion that the lumen of the ATP synthase membrane rotor is the long-sought megachannel that triggers the onset of the mitochondrial permeability transition is found to be inconsistent with its actual structural and functional properties.

    The mitochondrial permeability transition pore activates the mitochondrial unfolded protein response and promotes aging

    Suzanne Angeli et al.
    Loss of the F-ATP synthase c-subunit inhibits a pathological mitochondrial permeability transition pore that is coupled to a maladaptive mitochondrial unfolded protein response while also extending lifespan.

    Molecular and topological reorganizations in mitochondrial architecture interplay during Bax-mediated steps of apoptosis

    Nicholas R Ader et al.
    Correlative microscopy and electron cryo-tomography on apoptotic HeLa cells reveal remodeling of outer and inner mitochondrial membranes, Bax cluster ultrastructure and ATP synthase reorganization in ruptured mitochondria.

    TORC2-dependent protein kinase Ypk1 phosphorylates ceramide synthase to stimulate synthesis of complex sphingolipids

    Alexander Muir et al.
    TORC2-Ypk1 signaling upregulates flux through the sphingolipid pathway not only by increasing the supply of long-chain base precursors, but also by increasing their use in synthesizing complex sphingolipids.

    Mechanical inhibition of isolated Vo from V/A-ATPase for proton conductance

    Jun-ichi Kishikawa et al.
    Cryo-EM structures of rotary V-ATPase reveal the ON-OFF switching mechanism of H+ translocation in the Vo membrane domain.

    Sequence co-evolution gives 3D contacts and structures of protein complexes

    Thomas A Hopf et al.
    Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.

    Convergent changes in muscle metabolism depend on duration of high-altitude ancestry across Andean waterfowl

    Neal J Dawson et al.
    Changes in pathways of lipid oxidation, glycolysis, and mitochondrial oxidative phosphorylation are common strategies to cope with high-altitude hypoxia, but some changes require longer evolutionary time to arise.

    Mitochondrial flashes regulate ATP homeostasis in the heart

    Xianhua Wang et al.
    Mitochondrial flashes counteract the imbalance of ATP supply-and-demand and constitute an auto-regulator of ATP homeostasis in the heart.

    A novel ATP dependent dimethylsulfoniopropionate lyase in bacteria that releases dimethyl sulfide and acryloyl-CoA

    Chun-Yang Li et al.
    A novel dimethylsulfoniopropionate lyase was identified, which catalyzes dimethyl sulfide releasing by a new mechanism and is found in several bacterial lineages, revealing its important roles in global sulfur cycling.

    Distinct mitochondrial defects trigger the integrated stress response depending on the metabolic state of the cell

    Eran Mick et al.
    Mitochondrial electron transport chain dysfunction triggers the integrated stress response due to an asparagine deficiency downstream of impaired NADH oxidation in proliferating myoblasts, but not in differentiated myotubes.
